Features

Three Points Support Headstock Spindle

The headstock casting is designed with one ball bearing and two tapered roller bearings supporting the full length of the spindle shaft.

Spindle bore sizes are available in 6”, 9”’ 10″, 12” , and 15”. Double chucks are available as options.

Gears and shafts are made from hardened and ground alloy steel, the spindle is made from forged, chrome alloy material.

One Piece Casting Bed/Base

The oversized 24” wide bedways are induction hardened and ground for long lasting accuracy.

One piece casting bedways and base offer rigidity and stiffness to the entire machine to enhance heavy cutting

Double Chuck Capability

The headstock is available with rear chuck adapter that allows double chucks to be mounted onto the headstock for holding extra long or heavy work pieces.

Machine Designed for High Productivity

The machine is built with 2 V and 2 flat bed ways with an extra way in front to add support to carriage travel. FANUC Oi-TF control and drive are used for its high reliability and excellent service. 4 gear change spindle speeds are provided for heavy cutting requirements.

Powered Tailstock and quill
